The 'This Morning' host has agreed to front the skating reboot alongside Phillip Schofield in January, but she's "worried" she's going to end up pregnant with her fourth child if history repeats itself because she carried two of her babies - Harry, eight, and Belle, six - while hosting the show in 2009 and 2011.

Speaking to OK! magazine, Jayne Torvill - who has worked on the show alongside Holly - quipped: "Holly told me she's a bit worried because every time she does 'Dancing On Ice' she gets pregnant. She's had all three of her children while hosting the show."

Holly's third child Chester, now three, was born in 2014 - three years after she left the show in 2011.

Although the 36-year-old television star is concerned that she'll fall pregnant, she's made no secret of the fact that she'd love to expand her family with her husband Dan Baldwin in the future.

She said recently: "They're real people with personalities, and when we're all sitting about the table, I sometimes find myself thinking, 'Why wouldn't you want more of this Holly?'"

However, it's something that she's in two minds about at the moment because the couple already have their hands full with the three youngster - even though she loves being pregnant and giving birth.

She added when asked if she'd have another baby: "I don't think so. I mean, I really don't think so.

"But it's like the wedding dress thing - you just don't want that stage of your life to be over. I loved being pregnant. I loved giving birth. I would give birth again tomorrow as it's just the most amazing, empowering, life-changing thing."
